Allow users to remove the word-suggestion/prediction bar

The bar takes up a decent amount of space on a phone, and especially for apps with such a short text box that editing is difficult (like facebook), extra space could be very useful. Unfortunately, reducing the keyboard height by percentage does not increase the height of facebook's texting box.
[It just occurred to me that the short facebook text box might be intentional and that any additional space is added to the part of the app above the texting box, which would be typical facebook lameness, but I doubt all relevant apps are like this. Plus, extra space on a screen (for an app other than the keyboard) can be useful regardless, and the current method of reducing keyboard height doesn't do much other than making it difficult to type.]
Lastly, I've also noticed that reducing the font size of word choices/suggestions does not decrease the size of the bar accordingly. It should.
More options in settings is never a bad thing.
